Abstract

OBJECTIVE:

This study compared sleep quality and stress-related symptoms between older beds (>/=5 years) and new bedding systems.

METHODS:

A convenience sample of healthy subjects (women = 30; men = 29) with minor musculoskeletal sleep-related pain and compromised sleep, but with no clinical history of disturbed sleep, participated in the study. Subjects recorded back discomfort and sleep quality upon waking for 28 consecutive days in their own beds (baseline) and for 28 consecutive days (post) on a new bedding system using visual analog scales. Following baseline measures, participant's beds were replaced by new, medium-firm beds, and they again rated their sleep quality and back discomfort. Stress was assessed by a modified stress questionnaire.

RESULTS:

Repeated-measures analysis of variance was used to treat sleep quality and efficiency and factored responses of the stress items. Results indicated that the subjects' personal bedding systems average 9.5 years old and were moderately priced. Significant (P < .01) improvements were found between pre- and posttest mean values in sleep quality and efficiency. Continued improvement was noted for each of the 4-week data gathering period. Stress measures yielded similar positive changes between pre- and posttest mean values.

CONCLUSION:

Based on these data, it was concluded that, in this population, new bedding systems increased sleep quality and reduced back discomfort, factors that may be related to abatement of stress-related symptoms.
